Ambur, 
India
261,614 people lived in Ambur in 2025. It is the 2226th largest of the world's 12,138 cities, and the 362nd largest in India.
Like every city on this site, Ambur is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

How Ambur grew
For every 10 people in Ambur in 1980, there were 39 in 2025.
On the UN's projection it will have 308,508 people in 2050. It passed 250,000 people between 2010 and 2015. The UN first counts it as a city in 1980, when it passed 50,000 people.

How to read this: each column is one of the UN's five-yearly estimates, 1975 through 2050, and taller means more people. Where a column is hatched the year has not happened yet. The strip under the columns is the UN's own confidence in each figure, palest where it is least sure; where it is blank the city was not on the list at all.

Where it is
How to read this: every dot is one of the 2,054 cities in India in 2025, and a dot's area is how many people live there, the biggest being New Delhi. The ringed dot in colour is Ambur; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Ambur covered 38 km², and buildings, roads and other built-up land covered 5.2 km² of it. That is 20 m² of built-up land for each person, about a square 4 by 4 metres. Since 1995, its built-up land has grown to 2.9 times its size, and its people have grown by 43%.
How to read this: pale is the whole of the city's land; the stronger square inside it is what is actually built on. The three are drawn to the same scale, so a larger square really is more land, and hatching means the year is the UN's projection rather than a count.

How to read this: the number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.
Apparatus
Sources and method
The figures for Ambur are the UN's own, at five-year steps: an estimate for each of 1980 to 2025, then projection to 2050. Projected years are drawn hatched, and the UN publishes no range of uncertainty for a city. What a city means here, how the UN measures one, and why that number can differ from the one Ambur publishes about itself: how the figures here are put together.
